High quality!
I am not a seasoned programmer, so I cannot compare this to other resources available. Regarding the book itself, though, it is very high quality. The book itself is a hard cover with very high production values. Everything is illustrated and easy to understand. Like I said, I cannot vouch for the nitty-gritty that an expert might be able to, but from my perspective, this is a great place to start as a beginner.

Witty introduction. Not detailed, but technically accurate
Format: Kindle
I loved this book! I am a programmer and I have read several books about AI. This is an introduction for the general public. It does not have many technical details, but it is technically accurate. The writing is clear and understandable. It is also hilarious, with cute illustrations.
I think it has more technical details and more interesting, on-point examples than some reviewers appreciate. They see the jokes and illustrations, and they don't notice how much technical information comes along with them. For example, she describes some fascinating parallels with biological evolution and AI systems discovering method of locomotion on their own, such as making yourself into a tower and then toppling over in the direction you want to go. The author points out this is how some species of grass propagate their seeds, one stem-length, each growing season.
This is a short technical book. I like that! It reminds me of the classic "How to Lie With Statistics," by Darrell Huff, 1954, 142 pages. Everyone who wants to understand statistics should read this. It is also hilarious, it also has cute illustrations, and it is also one of the best introductions to the subject ever written.

Funny and scary, but with a bit of reassurance
Format: Kindle
Reassuring and disturbing at the same time, this book exposes the flaws and risks of AI, while pointing out the weaknesses that make it incapable of taking over the world.
The examples of AI foolishness entertain and startle. AI's missteps and errors and the real harm they cause provide a warning that is easier to absorb when leavened with the humor.
So what happens if I end this review with a bit of AI-generated predictive texting? Here goes:
This is a story out of India and I am not sure if I can make it to the wrong email address. Please let me know if you have any questions. I look forward to hearing from you.
